UNITED STATES PATENT GFFICE.

CHARLES E. FERRIS, OF EATON RAPIDS, MICHIGAN.

Patented Apr. 23, 1918.

LUTE.

1,263,398. Specification of Letters Patent.

No Drawing.

To all whom it may concern Be it known that I, CHARLES E. FERRIS', a citizen of the United States, residing at Eaton Rapids, in the county of Eaton and State of Michigan, have invented certain new and useful Improvements in Lute, of which the following is a specification.

This invention relates to improvements in luting composition and it is the principal object of the invention to provide a lute capable of being used for effectually closing opening or ruptures in cooking utensils, receptacles, etc., without the aid of an acid or an implement, or the roughening of the surface to which the lute is to be applied.

As an object of equal importance, the invention aims to provide a lute which may be effectually used by unskilled persons for mending or repairing various articles, thus, affording an exceedingly convenient and desirable household article.

The invention consists, furthermore, in the ingredients of the material as well as the relative proportions of the same, all of which will be more fully described in the following specification, and then finally embodied in the clauses of the claim, which are appended to the specification and which form an essential part of the same.

Having more particular reference to the improved luting composition, the same in its preferred embodiment includes,-

Brimstone or sulfur 60 parts by volume.

Aluminum (powdered) 40 parts by volume.

In producing the improved lute I preferably employ the following process:

The sulfur and aluminum are placed in a heavy steam jacketed retort suitable for the purpose and provided with an automatic agitator. The retort is then heated by steam units to a temperature varying between 115 F. and 537 F.; the alloy being subjected to this heat for a period of time varying between 25 and 10 hours. Subsequent to this, the lute is permitted to cool whereupon it is then broken up and subjected to a second I heating, the same of course, being placed in a suitable steam jacketed retort. During the second heating step, the lute will be melted and run into molds and shaped for convenience in using.

Application filed January 26, 1918. Serial No. 213,924.

Instead of molding the lute, the same may of course be used in powdered form, such as conditions or preference may dictate.

To use the improved lute, the article to be mended is placed over a source of heat, such as a small flame or the like and when heated to the. proper degree is cut by the solder over the point at which the rupture or opening occurs. The lute is of course smoothed as it is dropped upon the article receiving the same, and should the opening or rupture therein be of unusual size, it may be permitted to cool for a suflicient period of time whereupon a second coating or application of the lute may be applied.

From the foregoing, it will be readily understood by workers skilled in the art that I have provided an exceedingly efi'ective soldering compound which may be used for mending or repairing tin ware, granite ware, aluminum, copper, or in fact, practically any article desired; due to the simple manner in which the lute is applied, the same may be used by various persons, such as housewives, etc., unskilled in the application of the same.

I claim:-

1. A lute consisting of sulfur 60% and aluminum 40%. v

2. The herein described process for producing a luting composition consisting in placing sulfur 60 parts and aluminum 40 parts in a steam jacketed retort and subjecting the same to a heat varying between 115 F. and 537 F. for a period of time varying between 2 and 10 hours, whereupon the material is permitted to cool and is then remelted. I

3. The herein described process for producing a luting material consisting in placing sulfur 60 parts and aluminum 40 parts in a steam jacketed retort and subjecting the same to a heat varying from 115 F. to 537 F. for a period of time varying between 2% hours and 10 hours, whereupon the same is permitted to cool and is then broken and powdered.

In testimony whereof, I afiix my signature hereto.

CHARLES E. FERRIS.
